RE: Securities Subscription Agreement

Ladies and Gentlemen:

This agreement (the “Agreement”) is entered into on March 12, 2021 by and between DHIP Natural Resources Investments, LLC, a Delaware limited liability company (the “Subscriber” or “you”), and Integrated Rail and Resources Acquisition Corp., a Delaware corporation (the “Company”, “we” or “us”). Pursuant to the terms hereof, the Company hereby accepts the offer the Subscriber has made to purchase 7,906,250 shares (the “Shares”) of Class B common stock, $0.0001 par value per share (the “Class B Common Stock”) up to 1,031,250 of which are subject to forfeiture by you if the underwriters of the initial public offering (“IPO”) of units of the Company (the “Units”), do not fully exercise their over-allotment option (the “Over-allotment Option”). The Company and the Subscriber’s agreements regarding such Shares are as follows:

1. Purchase of Shares. For the sum of $25,000, which the Company acknowledges receiving in cash, the Company hereby issues the Shares to the Subscriber, and the Subscriber hereby purchases the Shares from the Company, subject to forfeiture, on the terms and subject to the conditions set forth in this Agreement. Concurrently with the Subscriber’s execution of this Agreement, the Company shall, at its option, deliver to the Subscriber a certificate registered in the Subscriber’s name representing the Shares (the “Original Certificate”), or effect such delivery in book-entry form.

2. Representations, Warranties, and Agreements.

2.1 Subscriber’s Representations, Warranties and Agreements. To induce the Company to issue the Shares to the Subscriber, the Subscriber hereby represents and warrants to the Company and agrees with the Company as follows:

2.1.1 No Government Recommendation or Approval. The Subscriber understands that no federal or state agency has passed upon or made any recommendation or endorsement of the offering of the Shares.

2.1.2 No Conflicts. The execution, delivery and performance of this Agreement and the consummation by the Subscriber of the transactions contemplated hereby do not violate, conflict with or constitute a default under (a) the formation and governing documents of the Subscriber, (b) any agreement, indenture or instrument to which the Subscriber is a party, or (c) any law, statute, rule or regulation to which the Subscriber is subject, or any agreement, order, judgment or decree to which the Subscriber is subject.

2.1.3 Organization and Authority. The Subscriber is a Delaware limited liability company, validly existing and in good standing under the laws of Delaware and possesses all requisite power and authority necessary to carry out the transactions contemplated by this Agreement. Upon execution and delivery by you, this Agreement is a legal, valid and binding agreement of Subscriber, enforceable against Subscriber in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, fraudulent conveyance or similar laws affecting the enforcement of creditors’ rights generally and subject to general principles of equity (regardless of whether enforcement is sought in a proceeding at law or in equity).

2.1.4 Experience, Financial Capability and Suitability.

(a) Subscriber is: (i) sophisticated in financial matters and is able to evaluate the risks and benefits of the investment in the Shares and (ii) able to bear the economic risk of its investment in the Shares for an indefinite period of time because the Shares have not been registered under the Securities Act of 1933, as amended (the “Securities Act”) and therefore cannot be sold unless subsequently registered under the Securities Act or an exemption from such registration is available. Subscriber is capable of evaluating the merits and risks of its investment in the Company and has the capacity to protect its own interests.

(b) Subscriber must bear the economic risk of this investment until the Shares are sold pursuant to: (i) an effective registration statement under the Securities Act or (ii) an exemption from registration available with respect to such sale. Subscriber is able to bear the economic risks of an investment in the Shares and to afford a complete loss of Subscriber’s investment in the Shares.

2.1.5 Access to Information; Independent Investigation. Prior to the execution of this Agreement, the Subscriber has had the opportunity to ask questions of and receive answers from representatives of the Company concerning an investment in the Company, as well as the finances, operations, business and prospects of the Company, and the opportunity to obtain additional information to verify the accuracy of all information so obtained. In determining whether to make this investment, Subscriber has relied solely on Subscriber’s own knowledge and understanding of the Company and its business based upon Subscriber’s own due diligence investigation and the information furnished pursuant to this paragraph. Subscriber understands that no person has been authorized to give any information or to make any representations which were not furnished pursuant to this Section 2 and Subscriber has not relied on any other representations or information in making its investment decision, whether written or oral, relating to the Company, its operations and/or its prospects.

2.1.6 Regulation D Offering. Subscriber represents that it is an “accredited investor” as such term is defined in Rule 501(a) of Regulation D promulgated under the Securities Act and acknowledges the sale contemplated hereby is being made in reliance on a private placement exemption to “accredited investors” within the meaning of Section 501(a) of Regulation D promulgated under the Securities Act or similar exemptions under state law.

2.1.7 Investment Purposes. The Subscriber is purchasing the Shares solely for investment purposes, for the Subscriber’s own account and not for the account or benefit of any other person, and not with a view towards the distribution or dissemination thereof. The Subscriber did not decide to enter into this Agreement as a result of any general solicitation or general advertising within the meaning of Rule 502(c) of Regulation D promulgated under the Securities Act.

2.1.8 Restrictions on Transfer; Shell Company. Subscriber understands the Shares are being offered in a transaction not involving a public offering within the meaning of the Securities Act. Subscriber understands the Shares will be “restricted securities” within the meaning of section (a)(3) of Rule 144 promulgated under the Securities Act (“Rule 144”), and Subscriber understands that the Certificates (as defined in Section 3.3) or book-entries representing the Shares will contain a legend in respect of such restrictions. If in the future the Subscriber decides to offer, resell, pledge or otherwise transfer the Shares, such Shares may be offered, resold, pledged or otherwise transferred only pursuant to (a) registration under the Securities Act covering such offer, resale, pledge or other transaction or (b) an

- 2 -

available exemption from registration. Subscriber agrees that if any transfer of its Shares or any interest therein is proposed to be made, as a condition precedent to any such transfer, Subscriber may be required to deliver to the Company an opinion of counsel satisfactory to the Company. Absent registration or an exemption, the Subscriber agrees not to resell the Shares. Subscriber further acknowledges that because the Company is a shell company, Subscriber may not be able to rely on Rule 144 promulgated under the Securities Act with respect to the resale of the Shares until one year following consummation of the initial business combination of the Company, despite technical compliance with the requirements of Rule 144 and the release or waiver of any contractual transfer restrictions.

2.1.9 No Governmental Consents. No governmental, administrative or other third-party consents or approvals are required, necessary or appropriate on the part of Subscriber in connection with the transactions contemplated by this Agreement.

2.2 Company’s Representations, Warranties and Agreements. To induce the Subscriber to purchase the Shares, the Company hereby represents and warrants to the Subscriber and agrees with the Subscriber as follows:

2.2.1 Organization and Corporate Power. The Company is a Delaware corporation and is qualified to do business in every jurisdiction in which the failure to so qualify would reasonably be expected to have a material adverse effect on the financial condition, operating results or assets of the Company. The Company possesses all requisite corporate power and authority necessary to carry out the transactions contemplated by this Agreement.

2.2.2 No Conflicts. The execution, delivery and performance of this Agreement and the consummation by the Company of the transactions contemplated hereby do not violate, conflict with or constitute a default under (a) the certificate of incorporation or by-laws of the Company, (b) any agreement, indenture or instrument to which the Company is a party, or (c) any law, statute, rule or regulation to which the Company is subject, or any agreement, order, judgment or decree to which the Company is subject.

2.2.3 Title to Securities. Upon issuance in accordance with, and payment pursuant to, the terms hereof, the Shares will be duly and validly issued, fully paid and nonassessable. Upon issuance in accordance with, and payment pursuant to, the terms hereof, the Subscriber will have or receive good title to the Shares, free and clear of all liens, claims and encumbrances of any kind, other than (a) transfer restrictions hereunder and other agreements to which the Shares may be subject which have been notified to the Subscriber in writing, (b) transfer restrictions under federal and state securities laws, and (c) liens, claims or encumbrances imposed due to the actions of the Subscriber.

2.2.4 No Adverse Actions. There are no actions, suits, investigations or proceedings pending, threatened against or affecting the Company that: (a) seek to restrain, enjoin, prevent the consummation of or otherwise affect the transactions contemplated by this Agreement or (b) question the validity or legality of any transactions or seeks to recover damages or to obtain other relief in connection with any transactions.

3. Forfeiture of Shares.

3.1 Partial or No Exercise of the Over-allotment Option. In the event the Over-allotment Option granted to the underwriters of the IPO is not exercised in full, the Subscriber acknowledges and agrees that it (or, if applicable, it and any transferees of the Shares (such transferees, the “Initial Stockholders”)) shall forfeit any and all rights to such number of Shares (up to an aggregate of 1,031,250 Shares, pro rata based upon the percentage of the Over-allotment Option exercised) such that immediately following such forfeiture, the Subscriber (and all other Initial Stockholders prior to the IPO, if any) will

- 3 -

own an aggregate number of Shares (not including any Shares issuable upon exercise of any warrants or any shares of Class A common stock, par value $0.0001 per share (the “Class A Common Stock”, together with the Class B Common Stock, the “Common Stock”) purchased by Subscriber or any other Initial Stockholder in the IPO or in the aftermarket) equal to 20% of the issued and outstanding Shares immediately following the IPO.

3.2 Termination of Rights as Stockholder. If any of the Shares are forfeited in accordance with this Section 3, then after such time the Subscriber (or Initial Stockholder or other successor in interest), shall no longer have any rights as a holder of such forfeited Shares, and the Company shall take such action as is appropriate to cancel such forfeited Shares.

3.3 Share Certificates. In the event an adjustment to the original certificates representing the Shares (the “Original Certificates”), if any, is required pursuant to this Section 3, then the Subscriber shall return such Original Certificates to the Company or its designated agent as soon as practicable upon its receipt of Notice (as defined in Section 6.2) from the Company advising Subscriber of such adjustment, following which a new certificate representing the Shares (the “New Certificate” and together with the Original Certificates, the “Certificates”), if any, shall be issued in such amount representing the adjusted number of Shares held by the Subscriber. The New Certificate, if any, shall be returned to the Subscriber as soon as practicable. Any such adjustment for any uncertificated securities held by the Subscriber shall be made in book-entry form.

4. Waiver of Liquidation Distributions; Redemption Rights. In connection with the Shares purchased pursuant to this Agreement, the Subscriber hereby waives any and all right, title, interest or claim of any kind in or to any distributions by the Company from the trust account, which will be established for the benefit of the Company’s public stockholders and into which substantially all of the proceeds of the IPO will be deposited (the “Trust Account”), in the event of a liquidation of the Company upon the Company’s failure to timely complete an initial business combination. For purposes of clarity, in the event the Subscriber purchases Units in the IPO or shares of Class A Common Stock in the aftermarket, any additional shares of Class A Common Stock included in the Units or shares of Class A Common Stock so purchased shall be eligible to receive any liquidating distributions by the Company. However, in no event will the Subscriber have the right to redeem any Shares into funds held in the Trust Account upon the successful completion of an initial business combination.

5. Restrictions on Transfer.

5.1 Securities Law Restrictions. In addition to any restrictions to be contained in that certain letter agreement (commonly known as an “Insider Letter”) by and between Subscriber and the Company to be dated as of the closing of the IPO, Subscriber agrees not to sell, transfer, pledge, hypothecate or otherwise dispose of all or any part of the Shares unless, prior thereto (a) a registration statement on the appropriate form under the Securities Act and applicable state securities laws with respect to the offer and sale of the Shares proposed to be transferred shall then be effective or (b) the Company has received an opinion from counsel reasonably satisfactory to the Company, that such registration is not required because such transaction is exempt from registration (i) under the Securities Act and the rules promulgated thereunder by the Securities and Exchange Commission and (ii) with respect to all applicable state securities laws.

5.2 Lock-up. Subscriber acknowledges that the Shares will be subject to lock-up provisions (the “Lock-up”) contained in the Insider Letter.

- 4 -

5.3 Restrictive Legends. Any Certificates shall have endorsed thereon legends substantially as follows:

“THE OFFER AND SALE OF THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS AND NEITHER THE SECURITIES NOR ANY INTEREST THEREIN MAY BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT COVERING SUCH OFFER, SALE, TRANSFER, PLEDGE OR OTHER DISPOSAL UNDER SUCH ACT OR SUCH LAWS OR AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT AND SUCH LAWS WHICH, IN THE OPINION OF COUNSEL, IS AVAILABLE.”

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A LOCKUP AND MAY NOT BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED DURING THE TERM OF THE LOCKUP.”

5.4 Additional Shares or Substituted Securities. In the event of the declaration of a share dividend, the declaration of an extraordinary dividend payable in a form other than Common Stock, a spin-off, a share split, an adjustment in conversion ratio, a recapitalization or a similar transaction affecting the Company’s outstanding shares of Common Stock without receipt of consideration, any new, substituted or additional securities or other property, which are by reason of such transaction distributed with respect to any Shares subject to this Section 5 or into which such Shares thereby become convertible shall immediately be subject to this Section 5 and Section 3. Appropriate adjustments to reflect the distribution of such securities or property shall be made to the number or class of Shares subject to this Section 5 and Section 3.

5.5 Registration Rights. Subscriber acknowledges that the Shares are being purchased pursuant to an exemption from the registration requirements of the Securities Act and will become freely-tradable only after certain conditions are met or the offer and sale of the Shares is registered under the Securities Act pursuant to that certain registration rights agreement to be dated as of the closing of the IPO by and between Subscriber, the Company, and the other parties thereto (the “Registration Rights Agreement”) prior to the closing of the IPO.

6.13 Counterparts.
